No claims discount protection
For every year you drive without making a claim, you get a no claims discount (which some call a ‘no claims bonus’). As it signifies you’re a safe driver, it can give a discount off your insurance.
But as soon as you have to make a claim where your insurer pays out, you’ll lose some or all of it. Which is a bit of a blow.
However, if you have no claims bonus protection, your no claims bonus is, well, protected. You can get it once you’ve accrued 3-4 years of no claims, and it lets you keep your discount even if you do have to make a claim.
